| Message | The bolts exceed stock bolts for strength (grade 11 if I recall correctly). The bolts are special order and are not carried by regular 'nut and bolt supply' companies.
 Perhaps the kids in your neighborhood will use a grade 3 bolt from Home Depot, but the folks who run 300degree prefer to design and engineer for a purpose, and enhance the design to increase the margin of safety. Before you go off spouting about things you know nothing about, (often), I'd recommend you do a touch of research.
